Asian Longhorned Beetle

Biology and Ecology

[image:] Collage of ALB damageAnoplophora glabripennis (ALB) is native to China and the Korean Peninsula.  In China, it is considered a major pest of several deciduous broadleaf tree species and causes severe damage from 21°--43°N latitude and from 110°--127°E longitude. The primary host trees of ALB in China include species of Acer (maple), Populus (poplar), Salix (willow), and Ulmus (elm), and it is reported to feed on more than 24 genera of hardwood trees. Eggs are laid beneath the bark and early larval instars feed under the bark, whereas later instars enter the wood. In China, ALB takes 1 or more years to complete development depending on the timing of adult emergence; later emerging adults lay eggs that may not hatch until spring a year later and some larvae require a chill period after they reach full size.

Northern Research Station scientists have been conducting research on biology and ecology of ALB since 1999.  This research has been directed toward providing the biological basis for predicting potential dispersal, developmental phenology, predicting population dynamics at low population levels, and attack rates in different environments.  Also, methods to increase the availability of insects for use in research have been developed.
